# Choosing a Model

> The picker, its filters, and the default model.

The model control in the composer footer opens the picker: the full catalog, each row showing the model, its privacy level, context window, and capabilities. A model served at more than one level gets one row per level, so GLM 5.2 appears at Private, Confidential, and Encrypted, and gpt-oss-20b at Anonymous and Confidential.

## Filters

| Control | What it does |
| :- | :- |
| **Search** | Matches names, IDs, model makers, capabilities, and descriptions. |
| **Use case** | Filters by capability: Reasoning, Tools, Files & vision, Long context. |
| **Privacy** | Filters by level. |
| **Sort** | Orders by Privacy, Context Window, or Price. The default is privacy order, strongest first. |
| **Favorites** | Starred models stay at the top. Press M, then 1 to 9, to jump to one. |

The Fusion card at the top of the picker selects two or three models for one prompt. See [Fusion](/web-app/fusion).

The catalog is live and shows exactly what your account can select. The full list is in [Model List](/models/all-models); [Choosing a Model](/models/choosing-a-model) covers which model suits which work.

## Nito Auto

**Nito Auto** picks the model for you. It is included in any paid plan and is the default on those plans. The picker lists its routes as **Nito Auto Low**, **Medium**, and **High**. See [Nito Auto and Prompt Enhancement](/web-app/nito-auto-and-prompt-enhancement).

## The Default Model

New chats start on your default model, set in **Settings** under Chat behavior. **+ New** resets the picker to it. If the default is no longer selectable, the picker falls back to the first available model.

The model you pick in a chat is remembered for that chat. `GLM 5.2` at Confidential is a different row from `GLM 5.2` at Private, and a chat holding Confidential or Encrypted history marks weaker rows **Incompatible** until you start a new chat.

## Reasoning Effort

Models that support reasoning expose an effort control in the composer: Off, Low, Medium, or High. Reasoning is off while Fusion is active and on models that do not support it.

## Free Plan

The Free plan selects from a small set of open-weight models, with a daily prompt allowance and a shorter context window. A paid plan opens every available open-weight and frontier model, including the Uncensored and Encrypted rows. See [Free Usage](/plans/free-usage).
